Clickjacking is a type of malicious attack where an attacker uses an invisible or transparent iframe to trick a user into clicking on a link or button on another website. This can be used to steal sensitive information, perform unauthorized actions, or compromise accounts.

Available Directives
1. **DENY**: Prevents any site from framing your content, including your own domain. 2. **SAMEORIGIN**: Allows only sites on the same origin (protocol, domain, and port) to frame your content. 3. **ALLOW-FROM (Deprecated)**: Allows only specific domains to frame your content. This directive is widely deprecated and should be avoided in favor of Content Security Policy's `frame-ancestors`.
Implementing the Header
You can easily implement the `X-Frame-Options` header on your web server or CDN. For example, in Nginx, you would add:
add_header X-Frame-Options "SAMEORIGIN";
In Apache, you would add:
Header always set X-Frame-Options "SAMEORIGIN"
Auditing Your Protection
